To all whom it may concern:

Be it known that I, FREDERICK J. GRUMME, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented a new and useful W'ire-Bound-Box-Blank- Machine, of

which the following is a specification.

The. object of my invention is to produce a machine by means of whichbox blanks,

composed of cleats and sheet material, may

be associated in such manner that the same may be folded to form thesides of a box.

he accompanying drawings illustrate my invention as incorporated in amachine especially designed for the production of wire bound box blankswherein the several sections of each box blank are connected andstrengthened by binding wires, Figure 1 being a plan with the usualstaple-forming and driving mechanism omitted; Fig. 2 a vertical sectionon the line 2-2 of Fig. 1; Fig. 3 a

fragmentary vertical section showing the sheet gaging and feedingmechanism; Fig. 4 a fragmentary detail of the right-hand end of thestructure shown in Fig. 3; Fig. 52). section, on a larger scale, on line55 of Fig. 1; Fig. 6 a fragmentary plan of the cleat interrupter andspacer; Fig. 7 a section on line 7.--7 of ,Fig. 6; Fig. 8 a section, online 88 of Fig. .1; Fig. 9 an elevation of another form of mechanism forwithdrawing the cleat-interrupter; and Fig. 10 a detail of the partsshown in Fig. 9.

In the drawings, 10 indicates the main frame of a machine provided withthe usual anvil bar 11, stapling mechanism 12 arranged above the anvilbar, and cleat guides 13, 13 arranged to deliver a succession of cleatsto the stapling plane and each provided with a friction-driven feedchain 14: adapted to yieldingly deliver cleats 15 through the cleatguides to the interrupter 16 which operates upon each cleat insuccession to temporarily detain it to permit the insertion between theforward end of the oncoming dent and the rear end of the precedingcleat, of a cleat-spacing member 17, the preceding cleats being underthe control of the spaced-cleat feeder chains 18 which last-mentionedchains are given step-by-step advancement by means of the ratchetmechanism 19 and connecting gear train 20 connecting said ratchetmechanism with the feed' chains in a manner so well known to the art asto need no further illustration.

Thus far the mechanism which I have described is common and well known,being illustrated more fully in Patent No. 985.996, issued March 7,1911,to Jason H. Green street. In the operation of the mechanism justdescribed, the spacing members 17 are moved into the space betweencleats by the" action of the pin upon the cam face 26 of the spacerfingers l7 and said spacers are automatically withdrawn from between thecleats, after the rearward cleat has passed under the control of thecleat feeder 18,by-

the action of the cam face 27 upon the pin or stop 28, and in thepresent form of machine these cleat spacers 17 are carried by a crossbar 29 supported by cross heads 31 upon the longitudinal guidebars 32so-that the cross bar 29' has a limited play lengthwise of the machine.

Arranged in frame 10 is a rock shaft 33 provided with a pair of upwardlyextend,

ing arms 34, 35 each of which is connected by a pin and slot connection136' with the cross bar 29. Attached to the arm 34 is a cord 137 whichis passed over-an idler 138 and provided at its lower end with a weight139 which normally tends to keep the cross I FREDERICK J". GRUMME, 0FINDIANAPOLIS, INDIANA, ASSIGNOR, BY MESNE ASSIG-N- the teeth of aconstantly rotating ratchet wheel 13 which is freely rotatable upon therock shaft 14, the ratchet wheel being carried by a sprocket wheel 45driven by a chain 46 connecting it through sprocket wheel 47 with aconstantly rotating shaft 48. Rock shaft l t-carries a radially,projecting arm 49 which lies within the path of movement of a finger 50carried by the pawl37. Shaft 44 also. carries arms 51 to which areconnected springs 52 which serve to normall hold the parts in theposition shown in Big. 7. Connected to arms 51 are links 53 which inturn are connected to {arms 54 carried by rock shafts 55 which are Theretracting operation of the inter rupter finger 16 is accomplished asfollows :-Normally, shoulder 42 of pawl 37 lies out of thepath ofmovement of theconstantly'moving ratchet'wheel 43 but as soon as -bar29-returns to the position shown in v F l and 8 the bracket'36 of arm 35engages pawl 37'so'as to move shoulder 42 into 1 the path of movement ofratchet 43 whereupon said ratchet serves to drive the pawl 37 quicklydownwardly. This. downward movementof the pawl 37 brings its finger 50into engagement with arm 49 of shaft 44,

thereby producing a short rocking. move ment of shaft-'44 and, throughits arms 51 and links 53 operating upon arms 54 of shafts 55 and causingthe arms 56 thereof to engage the cleat'interrupters 16 and withdrawthem from in front of the oncoming .cleats.

It is desirable immediately following the production of a completeblank, to interrupt the flow of cleats for the next blank just beforethe cleats pass into the control of the positive cleat feeder 18 and forthat purpose I provide a stop 60 which is automatically intermittentlymoved into the path of movement of a finger 61 carried by the cross bar29. In the production .of a four-sided box blank, this operation occursonce in the flow of each four cleats. Stop 60 is carried by a swingingarm 62- provided with a .pin'63 lying in a cam groove 64in a rotatingcam 65, which cam is provided with a series of pins. 66 (four in theresent instance) arranged to be engaged by a pawl 67 carried by crossbar 29. The main portion of cam groove 64 is such as to normally holdstop 60 out of the path of movement of stop 61 but at one point, asclearly shown in Fig. 1, this cam groove is formed so as to produce aswingof arm 62 so as to bring stop 60 into the path of movement of stop61.

Thus far the machine. while some minor details from the Grcenstreetmachine to which I have already referred, is, nevertheless,substantially the same as that machine, and my invention relates moreparticularly to the apparatus which I shall now describe.

Supported upon the anvil. bar 11 are guides 70 each of which is providedwith a run-way 71 in which is mounted a switch arm '72. The run-way 71formed to receive pin 73 carried by a swinging arm 74 differing inpivoted at 75 upon a bracket 76 mountedarm also carries at its rear endan adjustable block 80 which may be adjusted toward and from. gage 78,and carries vertically swingihgpawls 81. adapted to engagethe rear edgeof the sheet 79 but arranged to pass, freely beneath the sheet on thereturn or rearward movement of arm 74. Projecting rearwardly from eachguide 7 Q is a sheet supporting finger 82.

By this arrangement the sheet material is positively fed through themachine in synchronism with the cleats, the movement of this sheetfeeding and gaging mechanism being. dependent upon the movement of thecross bar 29 which is moved forwardly by the action of the spaced cleatsupon the cleat spacer 17 and as the end of this sheet feeding movementis neared, and after the first staple has been driven through theoncoming sheet into the cleat beneath, pin 73 reaches the cam surface71' of the cam slot 70 and passes beyond and beneath switch 72 where-'upon, the switch being returned by a spring 72', pin 73 in its returnmovement passes beneath switch 72 until the rear end of the stroke isreached, thusdepressing the'rear end of arm 74 and keeping the pawl 81and gage 78 from dragging upon the under side of the sheet material.

In the operation of machines of this type, I there is at times somedifficulty in the return movement of the cleat spacer 17 and for thatpurpose I arrange, adjacent the path of movement of such cleat spacer, aspring urged presser arm 91 which is pivoted at 92 on the main frame andserves to insure the I proper rojection of the cleat spacer between t 1eseparated cleats, as shown in Fig. 2.

In order that the arm 62 may be locked in its abnormal position for arequired length of time, so as to give proper spacing between blanks, Imount upon the under side of said arm .62 a pawl 93 which is adapted tobe engaged by a catch 94 when arm 62 is thrown to its abnormal position.In order to withdraw catch 94 at the proper time, said catch isconnected by a link 95 cleat guide. By this arrangement, whenever, thelast cleat of a series passes beyond the cam bar 98, it will bepermitted to rise, and

' rearward position by theweight-139, some difliculty has been found,owing t0 the jar of the weight, and it has not been found feasible todirectly operate the withdrawing means for the cleat interrupters bythis return movement and it is for that reason that the constructionshown in Fig. '7 is provided. I have found, however, that by theconstruction shown in Fig. 9, it is possible to directly operate thewithdrawing means for the cleat interrupters by mechanism which isdirectly connected with the returning mechanism for the cross bar 29,this apparatus being also of such character as to effect a variable pullupon the cross bar at different points in its movement and thus do awaywith the jar incident to the use of a weight of suflicient size toaccomplish desired results.

In this construction I provide the shaft 170, which is a constantlyrotating shaft acting by friction elements 171 upon the sprocket wheels172 which carry the preliminary feed chainslet. Upon this con.

stantly moving shaft 170 I mount a gear 176 which meshes with a gear 175mounted upon a stud shaft 17-7. Gear 175 carries a. friction element 178which frictionally engages an oscillating disk 179 journaled on the studshaft 177 and carrying a drum 180 of smaller diameter. Extendingradially from the periphery of this drum within disk 179'is a slot 181within which is slidably mounted a pin 182. Secured to this pin is aflexible link or thong 183, the opposite end of which is attached to oneof the arms 34 or 35. The disk 179 at one point is provided with a pin184 upon which rides an arm 185 carried by the rock shaft 44, said rockshaft carrying only the arms 51 and links 53 which connect with thelevers 54.

By this arrangement the pin 182 lies close to the circumference of drum180 when the parts are in the position shown in full lines,

and at this time the arms 34 and 35 are in the position shown in Fig. 2,the cross bar 29 being at the rear end of its stroke; i. 6., nearest thestapling plane. When the cross bar 29 is driven forwardly in themachine, by the action of the cleats on the cleatspacers 17, the disk179 will be dragged back against the action of its friction drivingmeans to the position indicated in dotted lines in Fig. 9, this movementdragging pin 182 to the outer end of slot 181 where the effect of thefriction drive upon the disk is the least upon the arms 34, 35. As soonas the cleat spacers 17 have been drawn out from between the cleats bythe action of the cam 28, the friction action of the element 178 upondisk 179 returns it 'to its initial position (moving in a clockwisedirection in Fig. 9) and as the movement of this disk nears its'end,there will be aslip of pin 182 inwardly in slot 181 so asto thusincrease the driving effect of the friction element 178 upon the arms.34, 35, and consequently increase the driving force upon the cross bar29, thereby giving greater force, although acting at a slower-speed,

upon the cleat spacers 17 to ..-drive them against the pins 25 and forcethe cleat spacers into the cleat guides in front of the interruptedcleat. Just as this final movement of the disk 179 takes place, pin 184engages the upper end of a slot formed in arm 185 so as to permit arocking of shaft 44 and a consequent operation of the cams- 56 towithdraw the interrupters 16. It will be seen that by this arrangementthe speed of return of the cross bar 29, close to the end of the returnmovement, is lessened, as

distinguished from the greater speed pro duced by the falling weight inthe structure shown in Fig. 2, and consequently by this arrangement Iavoid the jar which is incident to the operation of the weight.
